SIEGIFICATION forming part of Letters Patent No. 512,780, dated January 16, 1894.

Application filed October 16, 1893. Serial No. 488,297. (No model.)

To aZZ whom it may concern:

Be it known that I, FERDINAND WESEL, a

citizen of the United States, residing at Brooklyn, inthe county of Kings and state of New York, have invented certain new and useful Improvements in Printers Proof-Presses, of which the following is a specification.

- This invention relates to an improved proof press for newspaper, book and other printingoftices, by which not only satisfactory proofs can be taken of wood-cuts or half-tone plates, but also of any other matter for newspapers or books, the ink being supplied, as the operating carriage moves in one direction, by an automatic inking-roller, which spreads the ink over the form, said inking-roller-being automatically lifted from the latter forthe insertion of the proof-sheet, as the carriage moves in an opposite direction, to cause the impression-roller to move over the paper for taking the proof.

My invention consists of a proof-press for printing-offices, which comprises astationary bed on which the matter from which the proof is to-be taken is placed, a reciprocating carriage guided on said bed and moved over the same by suitable means, an inking-roller supported in bearings of the frame of the carriage, an impression-roller also supported on said frame, and means by which the inking-roller and the. impression-roller are lifted alternately above the type or other matter on the bed and placed in contact with the same, so as to ink the type or other matter on moving the frame in one direction and take the impression when moving the frame in the opposite direction. The change of positionin the inking and impression -rollers is produced by stops located below the stationary bed, which engage alternatelyan oscillatingshifting-head by which the mechanism for changing the position of the inking andimpression-rollers is operated. The oscillating shifting-head is retained in either of its shifted positions by means of a suitable locking-device, so that the inking-roller and the impression roller are held in position during the forward or back ward motion of the same over the stationary bed until by'the stops the change of position of the inking-roller and the impression-roller is accomplished.

tive position of the same toward the station-- ary-bed is changed when the reciprocating carriage arrives at the opposite ends of said bed. Fig. 5 is a broken plan of Fig. 3, partly in horizontal section on line 55, Fig. 3. Fig. 6 is a detail vertical transverse section on line 6-6, Fig. 5.

' Similar letters of reference indicate corresponding parts.

Referring to the drawings, A represents the supporting frame of myimproved proof-press for printing-offices. The supporting-frame A is composed of standards a that are connected by the tie-rods a, the standards supporting at their upper ends the bed-plate B. On each side of the bed-plate B, and respectively above and below the same, are arranged guide-rails b, b on which the reciprocating carriage O is guided. Motion is imparted to the reciprocating carriage O by means of a transverse shaft D, which is provided with pinions d that mesh with fixed racks d supported on both sides of and outside of the ways I) of the bed-plate, as shown clearly in Figs. 1 and 2. Theshaft D is provided with a crank-handle D by the turning of which reciprocating motion is imparted to the carperfectly steady reciprocating motion can be imparted to the carriage. 7

In inclinedjournal bearings e of the carriage O are supported the inking-rollers E E,- which are permitted to rotate at the proper time in contact with a'large ink-transferring roller E that turns in bearings of the upright ICO standards 0' of the carriage, said transferring-roller receiving the ink by intermediate rollers E above the same from an ink-fountain E that is arranged above the latter. Any suitable inking-device by which the ink is transferred to the inking-rollers E E may be used, as I do not desire to confine myself to the special construction shown. Back of the inking'rollers E E is suitably supported a vertically movable roller F, which is guided in vertical recesses f of the standards or endpieces of the carriage, and which serves to impart the necessary impression to the proofsheet when taking the proof from the matter placed on the bed-plate B, At both ends of the supporting-frame A are arranged below the bed-plate B stationary stops G, which are preferably provided with anti-friction rollers G, which stops engage an oscillating shifting head or cam-plate 9 that is triangular in shape and keyed to atransverse rock shaft g which is supported in hangers of the standards or end-plates C of the carriage O. The oppositely inclined sides g 9 of the oscillating shifting-head or cam-plate g are placed alternately in contact with the anti-friction rollers of the stationary stops G, so as to impart thereby anoscillating motion to the shaft g. To the outer ends of the shaft 9 are keyed angle orbell-crank leversH pivoted at one-end to lifting-plates h, which are vertically guided by center slots h which receive the crankshaft D, said lifting-plates being provided at the top with inclined faces 72 that engage the projecting ends or trunnions e of the inking-rollers E E so as to raise or lower the same in the inclined journal bearings e of the upright standards or end-plates of the carriage C, when the lifting-plates h are raised or lowered. The opposite ends of the levers H are connected by sectional adjustable pivot rods h with the projecting ends of the shafts or trunnionsf of the impression-roller F, which are received in the recesses f, the proper distance of the impression-roller from the anglelevers and consequently from the bed-plate being regulated by suitable right and left hand screws, turn-buckles, or other suitable devices such as H The bed-plate B is pro; vided at each side of its opposite ends with stationary releasing-hooks or wedges I, which serve to engage the spring-actuated bolts or pins 5 that are guided in openings in the keepers I which are applied to the upright standards of the carriage, each of the springactuated bolts or pins engaging either one or the otherof recesses or sockets j in the inner sides of the angle levers h after the change in the positions of the inking and impressionrollers, as the same arrive at the opposite ends of the bed-plate, is accomplished.

The operation of my improved proof-press is as follows: By turning the crank D and moving the carriage C in the direction from right to left, the inking-rollers E E are moved over the face of the type or other matter on the bed-plate B, so as to transfer the required quantity of ink to the same. When the carriage O arrives at the left-hand end of the bed-plate, the spring-actuated locking-bolts or pins 1', t', at the left-hand end of the machine are moved in contact with the inclined inner faces of the stationary hooks I at that end, so as to be withdrawn from the upper ones of the recesses or sockets j in the anglelevers H, and accomplish .the oscillating of said angle-levers. As soon as the bolts are retracted, the inclined side g" of the shifting head or cam-plate g, comes in contact with the stationary stops G and moves the same from the position shown in Fig. 3 into the position shown in Fig. 4 and when the bolts are released from the hooks on the return of the carriage they will spring into the lower recesses j. By the oscillating motion of the angle-levers H, the lifting-plates h and rods h by which the angle levers arcconnected with the inking-rollers E, E, and the impression-roller F are operated, :and thereby the inking-rollers raised bodily in their inclined recesses in the carriage C, so as to be sufiiciently above the face of the typeor other matter as not to contact therewith. The carriage O with its inking-rollers E, E, and impression-roller F is now at the left-hand end of the bed-plate. The proof -sheet is now placed on the type or other matter on the bed-plate and the carriage 0 moved in the oppositedirection by turning the crank-handle D and the parts are again locked in position as above stated. As the impressionroller F moves in contact with the face of the type or other matter from which the proof is to be taken, pressureis exerted on the proofsheet, so that a clear and sharp impression is obtained. When the carriage G arrives at the right-hand end of the bed-plate, the inclined side g of the shitting-head or ca-mplate g, is placed in contact with the stationary stops G at that end, so that the head or cam-plate is oscillated, and by the intermediate mechanism, the position of the inkingrollers E, E, and impression-roller F is again changed, so that the former are broughtdown on the face of the type or other matterflvlhile the impression-roller is lifted above thesame, as shown in Fig. 1. Immediately preceding the contact with the stops, however, the locking-bolts t, t, are withdrawn from the lower recesses j of the angle-levers by the stationary-hooks I, I, at that end of the bed-plate, so that the shifting motionof the inking-rollers and the impression-roller can take place. As soon as the carriage O is moved from the right to the left again, by a reversal of the motion of the crankshaft D, the locking-bolts or pins e', t, engage the upper recesses or sockets j in the angle levers and hold thereby the inking-rollers and the impression-roller in the position to which they are set by the oscillating shifting-head or camplate g. In this manner, by the alternating reciprocal motion IIO of the carriage C from one end of the bedplate to the other, and back again, a perfect proof is taken from the matter placed on the bed-plate, the shifting or changing of position of the inking-rollers E, E and the impression-roller F taking place in an automatic manner by the action of the statio l1ary stops G on the shifting head or cam-plate and intermediate mechanism. Any number of proofs may be taken by simply'repeating the forward and backward motion of the carriage over the matter on the bed-plate. The supply of ink is regulated from time to time in the same manner as with the well-known inking-attachments in general use for printingoffices.

I am aware that proof-presses have been used heretofore, in which a stationary inking-attachment was arranged at one end of the press, and in which the bed-plate with the type or other matter placed thereon was made horizontally movable, so as to pass be-" low the inking-rollers. After the type or other matter was supplied with ink, the impression was taken by placing a proof-sheet on the same and passing an impression-roller by hand or otherwise over the same. In my improved press the inking attachment is made a part of the carriage G, which is moved in the one or the opposite direction over the stationary bed-plate, and the position of the inking-rollers and of the impression-roller, relatively to the type or other matter from which the proof is to be taken, is changed automatically when the carriage arrives at the ends of the bed-plate, so that a very clear and sharp proof is taken, even by inexperienced hands, by the simple movement of the carriage from one end of the bed-plate to the other, and back to its original position.

Any matter such as wood-cuts, half-tone plates, and galleys containing newspaper or book-matter, can be placed on the bed-plate and by a few turns of the crank-handle clear impressions can be taken from the same, in

which defects in the cuts or in the type can be readily detected at once.

Having .thus described my invention, I claim as new and desire to secure by Letters Patent- 1.
